QR codes make any center more engaging! This pack includes 8 camping-themed centers for practicing addition and subtraction. All centers have self-checking QR codes and are available in both color AND black and white. Each center comes with a direction sheet so your students should be able to do these activities independently. Here are the centers included along with the Common Core alignment:

-Fireside Fact Families: Students find the missing addend in a fact family and write the corresponding equations (1.OA.4, 1.OA.6, 1.OA.8, 2.OA.2)
-We’re Going on a Doubles Hunt: Played like I Spy- students walk around the room solving doubles and near-doubles problems (1.OA.6, 2.OA.2)
-Fishing for Sums: Solve the addition problems and match the sum with the correct number header (1.OA.6, 2.OA.2)
-Fishing for Differences: Solve the subtraction problems and match the difference with the correct number header (1.OA.6, 2.OA.2)
-Packing Up Subtraction Sort: Sort subtraction equations based on whether they are true or false (1.OA.6, 1.OA.7, 2.OA.2)
-Shine a Light on Missing Addends: Match each addition problem with the correct missing addend card (1.OA.4, 1.OA.6, 1.OA.8, 2.OA.2)
-Acorn Addition Match-Up: Match the addition problems with the correct answer (1.OA.6, 2.OA.2)
-S’more Subtraction Match-Up: Match the subtraction problems with the correct answer (1.OA.6, 2.OA.2)

Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = ▯ - 3, 6 + 6 = ▯.
Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 - 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.
